HANGER.

Application filed Apri1 1 9, 1923. Serial No. 633,197.

and resident of New York, in the County of New York and State of New York, have invented certain new and useful Improvements 111 Door Hangers, of which the following is a specification.

This invention relates means for door hangers.

My invention is designed for use in conto lubricating nection with door hangers of the ball'bear 111g construction wherein steel balls of a hanger strap are arranged in the coacting grooves of a supporting track on which the hanger strap is free to slide horizontally.

An object of my invention is to provide a novel, simple, reliable and inexpensive means for lubricating the ball-bearings of the hanger, whereby to set up maximum freedom of action of the bearings and permit the hanger strap to move rapidly with respect to said bearings.

A still further object of my invention is to provide a lubricating means of this character which will automatically operate to keep the bearings supplied with just the sufficient quantity of lubricant, and without possibility of gumming the bearings by an oversupply of lubricant.

A. still furtherobject of the invention is to provide a device of this character which can bequickly applied to or removed from the track of the hanger as the occasion demands.

The various important features will be Inn-ticularly pointed out hereinafter in connection with a detailed description of a number of embodiments ofmy invention which I have selected for illustration in the accompanying drawings. in which similar reference characters indicate corresponding parts in the several views.

In the drawings:

Figure 1 is a front elevation of a door hanger showing my invention applied thereto, parts being shown in section.

Figure 2 is a section taken on the line 2-2 of Figure 1.

Figure 3 is a longitudinal section through a portion of the track showing a slightly modified form of the invention.

Figure 1 is a section taken on the line 4et of Figure 3.

Flgure 5 1s a perspectlve view of the wick shown in Figures 1 and 2.

, In carryingthe invention into practice,

I employ a hanger consisting of a fixed horizontal track 10 formed of. steel and provided with an upper V-shaped groove or ball-race 11, and a lower V-shaped groove or ball-race 12. While I have herein shown and particularly described a track having upper and lower ball-races, it shall be understood that this is not to be construed as a necessary limitation. There are cases wherein a single ball-race may be employed, and there are other cases wherein three or more of such races are employed. In either instance, my invention can be properly. correlated with the bearings. of the hanger, so that my invention willoperate with maximum efiiciency against the bearings. Neither do I wish to limit myself to the shape or form of the bearing grooves or race-ways herein shown. I prefer the men-,

tioned V-shaped grooves because the walls thereofare disposed at a tangent tothe balls, to lessen the resistance and friction between the relatively moving parts of the structure, and cause the hanger to operate with highest efliciency. f V i C o-acting with the track 10 is a channel bar 13 having horizontal flanges, 14 and 15, correlated tothe grooves 11 and'12 and respectively provided with similar grooves 16 and 17. 'Ihesegrooves 11, 12, 16 and 17 are associatedwith bearing balls 18. At the apex of each :of the grooves 11 and 12 and extendingoin the length of the track and in longitudinal relation to said grooves, are dovetailed channels 19. In the channels are removable correspondingly formed wicks 20. These wicks are formed of felt or other suitable well known absorbent material which operates to take up a liquid extend to the'top front edge of the track,

and same are disposed so that the nozzle of an'oil can or the like may be readily projected thereinto when it is desired to supply the respective passages and said wicks with a lubricant. The passages 22 extend above thepassages 21, and in consequence thereof,

they act as wells for the lubricant and permit the. latter-to be gradual-1y fed to said passages 21 to be finally taken up by capillary attraction by the wicks20. V

The wicks 20 extendxintolthe ball grooves or race-Ways of the track for a distance to warrant free rolling contact of the bearing balls therewith, thus inducing apcapillary In the modified form of my invention shown in Figures 3-.and 4 of the drawings,

theltrack 10, in lieu of having ,the channels 19 referred to in Figures 1 and 2, I provide the trackwith passages 23 suitably spaced apart and having a strip of wick material threaded't-herethrough. I thread this strip so that spacedportions thereof are respectively arranged at opposite sides of ,the track as shown at 24 and 25. These portions '24 and 25; projectinto the ball-races of the track and they are'adapted' to come in free rolling contact with the bearing balls. The track is provided with relatively diverging passages 2626 which merge together at V the upper front edge of the track. The opposite ,ends of these passages open into the adjacent passages 28v and against the transverse leads 27 :of .the' wick material. The terminals 28 of the wick material. may be wedged into suitable recesses 29 in the track so as .to'secure the material in a relatively fixed position.

While I have herein fully shown and de scribed, and have pointed out in the appended claims certain novel features of construction, arrangement, and operation which characterize my 111Ve11i31011,'lt will be understood by; those skilled in the art that various omissions, substitutions, and changes in forms, proportions, sizes, and details of the device, of the materials used, and of their operation may be made without departing from. my; invention.

What I claim as my invention is:

1. A structure of the class described comprising a plurality of relatively sliding members, anti-friction" bodies interposed between said members, and a Wick-of absorbent material extending lengthwise of t-hemembers and positioned with respect to said bodies so that the latter are in constant tree rolling Contact therewith, and means for supplying the wick with a lubricant.

E2.v Atrack'having a longitudinal ball-race, and a wick of absorbent material removably secured upon the track and arranged inlfixed parallel relation to theball-race so that a bearing in said ball-race will come in free rolling contact with said wick.

3. YA. track having a longitudinal ballrace, and a wick of absorbent material relmovably secured upon the track and arranged in fixed parallel relation to the ball- .race so that abearing in said ball-race will come in .free rollingcontact with-said wick, the track having. a passage opening at one end onto said wick and at its opposite end onto the't'ront upper edge of the track.

4. A door hanger including atrackhaving a race-way, a strip of lubricating ma terial extending into saidrace-way, a mem ber mounted to slide with respect to the track, andspherical bodies mountedin said raceway .andco-acting with the Walls there-
